Is turned off.

(2) The operation of the single room air conditioner 70 will be described.

The single room air conditioner 70 is controlled in conjunction with the operation of the supply unit 50 to which the single room type air conditioner is connected.

The operation of the private room air conditioner 70 can be controlled independently of the operation of the supply unit 50 by operating the private room remote controller 52 attached to the supply unit 50.

Therefore, even after the supply units 50 are installed, even if the air-conditioning capacity of the room becomes insufficient due to a change in the living environment or the like, the shortage of the air-conditioning capacity can be easily achieved by adding the single-room air conditioner 70. I can make up for it.

(3) The operation of the indoor unit 30 will be described.

The data of the average room temperature, the average target temperature, the operation mode, and the operation / stop (the state of each supply unit 50) sent from the center remote controller 10 are received.

If the stop command has not been received and all the supply units 50 have not been stopped, the difference between the average room temperature and the average target temperature is obtained.

The data of the outside air temperature sent from the outdoor unit 40 is received. An air-conditioning load is assumed based on the outside air temperature, the operation mode, the temperature difference, and the number of stopped operation of each supply unit 50, and the rotation speed of the compressor 42 and the rotation speed of the indoor fan 32 are determined according to the air-conditioning load.

When the stop command is not received from the indoor unit 30, the data of the compressor rotation speed and the operation mode sent from the indoor unit 30 are received.

When the compressor rotation speed is zero, the compressor 42 and the outdoor fan 43 are each turned off. If the compressor rotation speed is zero or more, the compressor 42 and the outdoor fan 43 are respectively operated.

When the operation mode is heating, a four-way valve (not shown) for switching the flow direction of the refrigerant is turned on to form a heating cycle. When the operation mode is cooling, the four-way valve is turned off and a cooling cycle is formed.

The temperature detected by the outside air temperature sensor 44 is read, and the data is sent to the indoor unit 30. When the stop command is received from the indoor unit 30, the compressor 42 and the outdoor fan 43 are each turned off.

It is determined with reference to the set operation mode setting conditions.

For example, when the average room temperature is lower than 23 ° C., the heating mode is set regardless of the outside air temperature. When the average room temperature is 23 ° C. or higher and lower than 28 ° C., the dry (dehumidification) mode or the blowing mode is set according to the outside air temperature. If the temperature is 28 ° C. or higher, the cooling mode or the air blowing mode is determined according to the outside air temperature.

(6) The operation of the air conditioning and ventilation unit 60 will be described.

Ventilation fan 6 to promote
Operation off 2 is selected. When the average temperature of all the rooms is lower than the average target temperature of all the rooms, the strong wind operation of the ventilation fan 62 is selected in order to increase the amount of outside air to increase the indoor temperature. When the average room temperature in all rooms is stabilized at the average target temperature in all rooms, the ventilation unit 6 is used to reduce noise.
2 is driven by a weak wind.

However, when the operation of the ventilation fan 62 is turned off, the difference (average temperature difference) between the average room temperature in all rooms and the average outside air temperature is calculated.

The operation state of the ventilation fan 62 is selected by comparing the temperature difference with the ventilation control condition for cooling / blowing stored in the internal memory of the air conditioning / ventilation controller 61.

That is, if the room is still hot, such as at the start of cooling, the operation off is selected as described above. However, if the average outside temperature is lower than the average room temperature in all the rooms, the outside air cooling is selected. Can be performed, the weak wind operation or the strong wind operation of the ventilation fan 62 is selected. Since the total heat exchanger has a heat exchange efficiency of about 60%, the remaining 40% of the non-heat exchange action enables external air cooling.

If the operation mode of the air conditioner body 20 is heating, the difference (average temperature difference) between the average target temperature in all rooms and the average room temperature in all rooms is calculated.

The operating state (off, weak wind, strong wind) of the ventilation fan 62 is selected by comparing the heating ventilation control condition stored in the internal memory of the air conditioning ventilation controller 61 with the temperature difference. Is done.

That is, when the average room temperature in all rooms is lower than the average target temperature in all rooms, for example, when the room is still cold, such as at the start of heating, the amount of outside air introduced into the room is reduced to reduce the rise of heating. Ventilation fan 6 to promote
Operation off 2 is selected. When the average room temperature of all the rooms exceeds the average target temperature of all the rooms, the strong wind operation of the ventilation fan 62 is selected in order to increase the amount of outside air introduced and lower the room temperature. When the average room temperature in all rooms is stabilized at the average target temperature in all rooms, the ventilation unit 6 is used to reduce noise.
2 is driven by a weak wind.

However, when the operation of the ventilation fan 62 is turned off, the difference (average temperature difference) between the average outside air temperature and the average room temperature in all the rooms is calculated.

The operating state of the ventilation fan 62 is selected by comparing the heating ventilation control condition stored in the internal memory of the air-conditioning ventilation controller 61 with the temperature difference.

That is, when the room is still cold, such as when heating is started, the operation is selected to be turned off as described above. However, if the average outside air temperature is higher than the average room temperature in all the rooms, the outside air heating is selected. Can be performed, the weak wind operation or the strong wind operation of the ventilation fan 62 is selected. In this case, since the heat exchange efficiency of the total heat exchanger is about 60%, the remaining 40% of the non-heat exchange action enables outside air heating.

If the operation mode of the air conditioner main body 20 is dehumidification, the ventilation fan is checked by comparing the ventilation control conditions for dehumidification stored in the internal memory of the air conditioning ventilation controller 61 with the average indoor humidity. 62 operating states (off, low wind,
Strong wind) is selected.

That is, when the average indoor humidity is still high, such as at the start of dehumidification, the ventilation fan 6 is used to reduce the amount of outside air introduced into the room and promote the dehumidification.
Operation off 2 is selected. As the average room humidity decreases, the weak wind operation or the strong wind operation of the ventilation fan 62 is selected to increase the amount of outside air introduced.

When the operation state is selected in this way, the operation of the ventilation fan 62 is actually controlled by the selected contents, and data representing the control state (operation / stop, air flow) is transmitted to the center remote controller 10. Sent (step 718).

When the operation stop command is received from the center remote controller 10, the operation of the ventilation fan 62 is stopped. Data regarding this stop is sent to the center remote controller 10.
